5 verses have
“gain”
in Edition Clear Qur'an by Talal Itani / Al-Anfaal (The Spoils of War)
8:30When the disbelievers plotted against you, to imprison you, or kill you, or expel you. They planned, and God planned, but God is the Best of planners.
8:41And know that whatever spoils you gain, to God belongs its fifth, and to the Messenger, and the relatives, and the orphans, and the poor, and to the wayfarer, provided you believe in God and in what We revealed to Our servant on the Day of Distinction, the day when the two armies met. God is Capable of everything.
8:60And prepare against them all the power you can muster, and all the cavalry you can mobilize, to terrify thereby God’s enemies and your enemies, and others besides them whom you do not know, but God knows them. Whatever you spend in God’s way will be repaid to you in full, and you will not be wronged.
8:69So consume what you have gained, legitimate and wholesome; and remain conscious of God. God is Forgiving and Merciful.
8:72Those who believed, and emigrated, and struggled in God’s cause with their possessions and their persons, and those who provided shelter and support—these are allies of one another. As for those who believed, but did not emigrate, you owe them no protection, until they have emigrated. But if they ask you for help in religion, you must come to their aid, except against a people with whom you have a treaty. God is Seeing of what you do.

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
